Performance and Application Analysis of ACRYLATES Paintings

Acrylic resin is a copolymer composed of methacrylate, acrylate and vinyl monomers. Compared with other synthetic macromolecule resin materials, acrylic resin materials have obvious advantages, such as light resistance, weather resistance, durability, heat resistance and so on. It will not change color at the temperature of 230℃, and has good acid and alkali corrosion resistance. It is more and more widely used in automobile, household appliances, construction, plastic products and so on. Acrylic numerical coatings can be divided into several different types according to different resin structures and production processes.


On the one hand, it is stable, including UV, acid and alkali resistance, chemical corrosion resistance and so on. Because of the existence of a-H, the oxidation resistance and UV resistance of acrylates are lower than those of methacrylates. Acrylic resin, using C-C bond as the main chain, has excellent oxidation resistance, acid-alkali resistance and hydrolysis resistance. On the other hand, it has the mechanical properties, including elongation, hardness, toughness and so on. These properties are largely affected by the molecular structure density of polymers. With the increase of side chain, the tensile strength and hardness of acrylic resin will decrease obviously, and the elongation and softness will increase obviously. Polymethacrylate (PMA) has a great limitation on the rotation of C-C main chain because of its methyl at a-position. There is no a-methyl in polyacrylate, and each chain can rotate around the main chain. This is the reason why the hardness and tensile strength of polymethacrylate are better, and the softness and elongation of polymethacrylate are worse than that of polyacrylate.
